dc.description.abstract
2-Ethylhexyl 4-methoxycinnamate is one of the UVB blocking agents more widely used in a variety of industrial fields. There are more than one hundred industrial suppliers worldwide. Given the enormous annual consumption of octinoxate, problems that arise due to the accumulation of this compound in nature should be taken into consideration. The GC-RT was used in this work with the aim of determining the vapor pressure, enthalpies of vaporization and octanol-air partition coefficient, for the BBP, DOP, E- and Z-EHMC esters. The results showed that Z-EHMC is almost five times more volatile than E-EHMC. Moreover, BBP, Z-EHMC and E-EHMC can be classified as substances with a relatively low mobility since they lie within the range of 8 < logKOA < 10 and 4 < log(PL/Pa) < 2, while DOP lies in the range of logKOA > 10 and log(PL/Pa) < 4, therefore, a low mobility can be expected. From these parameters, their particle-bound fraction and gas–particle partition coefficient were also derived.
